The pipeline of MR imaging and statistical analyses. Multicontrast MR imaging examinations including T1WI, DSI, and resting-state fMRI were performed to measure HV and SC of the iCB and iFC between the hippocampus and the PCC, respectively. A linear regression model was used to evaluate the correlation of HV with SC and iFC indices, where Y is the volume ratio of the hippocampus and X1 and X2 are the SC and iFC of the HP-PCC connection, respectively. HP indicates hippocampus; rsfMR, resting-state fMRI.

Relationships between HV and hippocampus-PCC SC and iFC indices in patients. We found a significant relationship between the volume ratio of the hippocampus (x-axis) and the mean GFA of the iCB (y-axis) (A) and between the volume ratio of the hippocampus (x-axis) and averaged z-value of the hippocampus (y-axis) (B) in the left hemisphere in patients with left MTLE+HS, whereas there were no correlations in the right hemisphere (C and D).
